[Successful treatment of an aortoduodenal fistula after operation on the abdominal portion of the aorta]

Gastrointestinal haemorrhage is a common cause of emergency admission of patients to surgical hospitals. Within the structure of nosological entities, not unreasonably referred to the rarest causes of gastrointestinal bleeding is the formation of an aortointestinal fistula whose early diagnosis is of paramount importance. The clinical picture may be different but it is mostly represented by gastrointestinal haemorrhage. The incidence of gastrointestinal fistulas following a surgical intervention ranges from 0.6 to 2.3%. Unless timely diagnosed and with incorrect therapeutic decision-making, the mortality rate amounts to 90%. In this article we present a clinical case report regarding successful treatment of a patient presenting with a secondary aortoduodenal fistula occurring 5 years after previously performed aortofemoral bypass grafting and complicated by relapsing intestinal bleeding and acute ischaemia of the right lower extremity.

[Antiviral therapy of chronic hepatitis C: 30 years success story]

Exactly 30 years ago, hepatitis C virus was identified. Over the years, tremendous success has been achieved in the treatment of hepatitis C, which is currently considered to be an almost completely curable disease. The review presents the main stages in the development of hepatitis C antiviral therapy, the efficacy of various treatment regimens. The greatest progress in treatment was noted over the past 5 years when drugs with direct antiviral action appeared and began to be widely used, including in Russia, which ensure the elimination of the virus in 90-95% of cases.

Issues for discussion: the distribution of anaphylactic reactions in children, especially early age, causes, clinical features and the complex life-saving activities.

[Study of animals with transplanted tumors]

A formula of temperature homeostasis of the body during inoculated tumor development was described. The basic data were temperature parameters of tumor S-45 inoculated to 180 rats subcutaneously and intramuscularly. Thermography was used as a method of investigation. An analysis of the results obtained led to a conclusion of a principal difference in the nature of heat processes in the body with tumors at different depths. In addition to it, the heat status of a tumor reflected the state of the vascular system making it possible to assess a necessary degree and nature of therapeutic exposure. Taking into account two periods of a heat status of the body one could choose the most effective therapeutic method during tumor development. The above material formed the basis for producing a heat model of tumor in order to improve methods of cancer diagnosis and therapy.
